I would vote FOR 110 again in a heartbeat. Prohibition doesn't work, is a waste of taxpayer money, and churns people through the criminal justice system. It should be no business of the government what you put into your body in your own private residence.

The whole point of ballot initiatives is to go over the head of the state legislature. It is a check on their power and the two party system. They have no right to reverse a ballot initiative.
